SPECIFICATION forming 'part of Letters ratent No. 707,650, dated August2e, 1902.

l Application filed November 22,1899. Serial No. 737,849. (No model.)

To all whom, t nw/y con/cern.-

and IIOMER P. ELLIOTT, citizens of the United States, residing atColumbus, in the county' of Franklin and State ot' Ohio, have invented acertain new and useful Improvement in Antifrictional Bearings, of whichthe following is a specication.

Our invention relates to the improvement Io of antifrictional bearings;and the objects Vof our invention are to hicle-axles andlike places ofsuperior construction and arrangement of parts, to provide improvedmeans for retaining the bearing-rollers in connection and in frictionalcontact With the surface of the spindle, and to produce otherimprovements the details of which will be more fully set forth herein--zo after. These objects we accomplish in the manner illustrated in theaccompanyingV drawings, in which- Figure 1 1s a view in elevation of aspindle,

showing in section the bearing parts which;

z 5 are connected therewith; ,and Fig. 2 is a face View of thespindle-shoulderring, which vwe employ in the manner hereinafterdescribed.-

Similar numerals refer to similar parts throughout the several views.

3o 1 represents an axle-spindle, which at its inner end is provided withthe usual shoulder 2 and which at its outer end isprovidedA with theusual reduced threaded extension 3. As indicated at 4 and 5, We form inthe periphery of said spindle at points on opposite sides of the centerof its length groovesjor channels, which are adapted for the purposeshereinafter set forth.

6 represents an inner end ring, which sur 4o rounds the spindle adjacentto and abuts provide an improved bearing of this class adapted for useon vel hinged ends.

this recess project the rounded ends of the Beit'known that We,FREDERICSSEAGRAVE projecting end pins 1l of bearing-rollers 12, the peripheriesor" which are in contact with the outer surface or periphery of thespindle. The outer pin projections 11 of the rollers 12 bear or areretained in a correspondinglyrecessed ring 13, which surrounds thespindle at a point adjacent to and on the inner side at 15. Thisstop-ring is adapted, as shown in the drawings, to have its innerportion seated in the groove 4, in which position it is secured by asuitable connection ot' the ends of its sections which are opposed tothe o Within the spindle-groove 5 we secure a sectional ring 16,corresponding in construction With the ring 14, against which is adaptedto abut a bearing-ring 17, corresponding in form and construction withthe ring 13. Into the recessed portion of this ring 17 are adapted`cessed portion of a ring 20, which surrounds `the outer-end portion ofthe spindle 1 and which is securedthereto through the lnedium loi'screws 2l. v20 We mount upon the unreduced endlof the 85 vspindle aball-carrying ring 22, which, as prescribed for the ring (5, is providedon its inner face and in itsupper portion with a groove Onthe outer'side of the ring or Vraceway 23, within which are retained, through themedium of a retaining-ring 24, 9o balls 25. Upon thethreaded extension 3of the spindle is adapted to be screwed a nut 26, the inner end flangeof which abuts, as shown, against the ring 22. This nut is preferablyretained against voluntaryrotation through the employment of aspring-dog 27, one end of which is secured centrally to the Vend of thespindle and the remaining or enlarged end of which is adapted to engagesockets or ,recesses formed partly in the end of the spinroo dle andpartly in the outer face of the nut.

While the bearing of the rollers 12 and 19 herein described is confinedWholly to the periphery of the spindle and is thus independent of aboxing, it is obvious that the spindle is adapted to be contained withina suitable cylindrical boxing, the end portions of which are indicatedat 28. It will be observed that the end portions ot these boXings are solocated as to have a bearing contact with the balls 8 and 25. It isobvious that any horizontal adjustment of this boxing may beaccomplished through the rotation of the nut 26 and that the balls 25and 8 are so arranged with reference to said boxing as to receive theend thrust in either direction. The means which we have employed forretaining the rollers in engagement with the periphery of the spindleare such as to insure a bearing con tact of the rollers and said spindleand avoid any frictional contact of said rollers with the boxing.

It is obvious that the outer end ring 22 and nut 26 might be formedintegral, this construction being shown, however, in an application forpatent executed and filed by us of even date herewith.

f It will be seen that by retaining the rollers in connection With thespindle in the manner herein described the bearing parts can readily beexposed to view and the rollers or balls removed or replaced, as may bedesired.

Having now fully described our invention, what we claim= and desire tosecure by Letters Patent, is

The combination with a spindle having peripheral groove, of a ringformed of semicircular sections hinged at their adjacent ends and havinga flange portion engaged in said
